Expression of procollagen α
(I) and glyceraldehydes-3-phosphate dehydrogenase (GAPDH) mRNA in normal and desmoid fibroblasts. Panel A: NF: normal fibroblasts; DF: desmoid fibroblasts; DFT: desmoid fibroblasts plus toremifene. Similar results were obtained in four separate experiments. In panel B the absolute counts, obtained by densitometric analysis, were converted to percentages of control value, assuming the untreated level of normal fibroblasts as 100%.
